    • A viewing instrument with a variable direction of view is disclosed generally comprising an outer instrument shaft, such as endoscope shaft, with a viewing element at its distal end, and an inner drive shaft within the outer shaft for moving the viewing element in order to change the direction of the view vector. First and second on-board actuators, such as motors, are arranged in the proximal portion of the instrument for rotating the outer and inner shaft, respectively, in order to rotate the viewing element through two degrees of freedom. In certain embodiments, the axes of the shafts are coincident, and the viewing element rotates about a rotational axis substantially perpendicular to shaft axes. In some embodiments, the axes of the motors are substantially parallel.
    • 通常包括具有可变视方向的观察仪器,其包括诸如内窥镜轴的外部仪器轴,在其远端具有观察元件,以及在外部轴内的用于移动观察元件的内部驱动轴,以便改变 视图向量的方向。 第一和第二板载致动器(例如马达)布置在仪器的近端部分中,用于分别旋转外轴和内轴,以便使观察元件旋转两个自由度。 在某些实施例中,轴的轴线重合,并且观察元件围绕基本垂直于轴线的旋转轴线旋转。 在一些实施例中,电机的轴线基本上是平行的。
